Firefox cannot connect to wss://...
I have deployed this software in a kubernetes cluster and it works just fine with a very basic nginx ingress controller.
But now I deployed it on a docker host with an nginx forwarding proxy and for some reason wss is not working.
I have port 80 and 443 exposed, but 80 only redirects to 443.
The upload stalls and Firefox error console says it cannot connect to wss://same-domain-as-webui.
The stdout says this line over and over;
[ 'https://same-domain-as-webui', 'wss://same-domain-as-webui' ]
(I have censored the domain to avoid abuse)
What am I missing?
